Heavy Duty Trucks


High fuel prices and escalating maintenance costs have long plagued fleet managers seeking new ways to maximize efficiency. Lithium-ion power systems from Xantrex can reduce fuel costs, engine wear and greenhouse gas emissions by eliminating the need for diesel or battery-powered APUs.

Xantrex Freedom eGen lithium-ion power systems eliminate the higher fuel burn and increased engine maintenance resulting from continuous idling, diesel APUs, and battery systems that rely on truck engine auto-starts to recharge. A Xantrex inverter charger, paired with a lithium-ion battery pack, can provide both DC and AC power to run sleeper cab hotel loads – including HVAC – with no need for auto-starts or extended engine operation.

A complete power ecosystem for your truck

Xantrex lithium-ion batteries provide nearly double the available capacity of traditional lead acid cells, allowing them to power hotel loads at rest stops without adding to fuel and maintenance costs. Daily driving keeps the batteries fully charged, while adding a rooftop solar panel ensures they stay topped up by offsetting parasitic sleeper cab loads. The end result is lower costs, reduced downtime, greater reliability and lower greenhouse gas emissions while assuring operator comfort in all climatic conditions for safer operation overall.

Long haul in comfort

An inverter charger, compared to an inverter, gives you even more freedom to run your electrical loads off your battery and charge your batteries when on the road.

Off-grid energy generation

Give yourself the freedom to generate energy in the most secluded locations. Shade is the enemy of solar panels. Tested to produce 70% of normal power in severely shaded conditions compared to almost no power from leading competitor technologies.

LiFePO4 vs Lead Acid

With the advances in technology, you can get more charge cycles and more energy per cycle from a LiFePO4 ebattery than a traditional AGM or Gel Cell lead acid battery.
